Q

what are flat irons

Q

how do rivers act as agents of change

A

river down cuts and creates terraces when the climate changes; they move across the valley before glaciers advance

Q

dunes do not equate to what? and why?

A

wind, the term dune refers to the shape

20
Q

how do humans act as agents of change

A

by removing or oversteeping slopes that cause mass wasting, dam failure, building buildings on cliffs, coastal construction

21
Q

.who championed geomorphology

A

william morris davis

22
Q

landscapes ____ overtime

A

evolve

23
Q

stages of evolution can be determined by… (WMD theory)

A

examining the characteristics of the landscape

24
Q

the characteristics of the landscape implies that ___ is the critical factor (WMD theory)

A

time

25
Q

what causes issue with this theory (WMD theory)

A

plate tectonics will “upset” the landscape

26
Q

what was G.K. Gilbert’s input about process geomorphology

A

landroms are balanced between resting framework and driving forces acting to alter the landscape

27
Q

what did G.K. Gilbert’s theory imply

A

time is but one part of may that affect the landscape alteration

28
Q

example of driving forces and resisting forces

A

rocks are the resisting framework, climate is the driving force. Rocks are eroding away but keeping the shape

29
Q

the landscape is changing but also staying in _____

A

equilibrium

30
Q

when landscapes are in equilibrium, the form ___ and the position ____

A

stays the same, changes

31
Q

when a landscape is in equilibrium, what will happen to the shape if nothing is added to the system

A

keeps same shape forever

32
Q

what is dynamic equilibrium

A

the balance between opposing forces that has a threshold. Once this threshold is overcome balance must be re-established under these new conditions

33
Q

steady time

A

no change over a short time

34
Q

graded time

A

small changes over longer time due to fluctuations in boundary conditions

35
Q

cyclic time

A

same changes occur over time. the average conditions with time can become flat, featureless plane

36
Q

base level

A

when erosion will occur

37
Q

what are the driving forces

A

climate, gravity and internal heat

38
Q

what is climate driven by

A

the sun, solar radiation interacting w earth’s major systems; Milinkovich cycles

39
Q

what does gravity determine

A

how much work will operate on all systems

40
Q

what does internal heat drive

A

plate motion/ tectonic activity

41
Q

what does internal heat control

A

the potential energy for work

42
Q

rocks under the surface can ____ when pressure is applied by the others with the addition of ____

A

bend, heat

43
Q

basin

A

extension

44
Q

ridge/valley

A

compression

45
Q

ridges are made up of what

A

more resistant rock types

46
Q

valleys have what type rock

A

shale
